Summary: | 碩士 === 國立彰化師範大學 === 電信工程研究所 === 98 === In this thesis, a quasi-lumped design of a suspended stripline (SSL) bandpass filter (BPF) exhibiting high signal selectivity is proposed. In the circuit, transmission zeros were implanted to enhance the stopband signal rejection. A sample BPF having an operation band of 6.77–7.33 GHz was fabricated and measured for performance verification of the proposed design.
A novel UWB bandpass filter (BPF) design using the suspended stripline. The filter composes of a low-pass and a high-pass circuit, both are implemented by SSL structures. A notch response structure might be implemented by a bandstop filter. The low-pass filter's cutoff frequency is designed at 10.6 GHz and the high-pass filter's cutoff frequency is set to 3.1 GHz. The bandstop filter using parallel capacitor and inductor connected in series to ground designed at 5.5 GHz. The quasi-lumped elements circuit models are developed to analyze these circuits' performance. Experiments are conducted, and good agreements are observed between the measurements and simulations.
